Sennheiser IE-40 Pro IEM

The high expectations placed on in-ear monitoring are effortlessly satisfied by the IE 40 PRO thanks to an advanced dynamic driver system. The innovative diaphragm delivers a warm sound, yet powerful and precise, even in extremely loud environments. Even at maximum sound pressure levels, the signal remains distortion-free and precisely defined. The IE 40 PRO is a superior monitoring device for musicians and DJs that adapts to every ear. A compact design combines a secure fit with excellent wearing comfort. It’s robust construction is designed to be suitable for the rigors of stage use from the connection to the cable duct.

The IE 40 PRO improves the way you perform by enhancing the way you hear.

Dynamic drivers of the next generation

Whereas most IEM systems use multi-driver solutions derived from hearing aids, the IE 40 PRO uses a next-generation dynamic single-driver. As it turns out, the frequency range does not have to be split up into sections but remains harmonious as a whole. It sounds “well-rounded”, and its frequency spectrum has been considerably expanded. There are no distortions because the special diaphragm – unlike the more rigid drive principle of the multi-way drivers – resonates easily even at maximum sound levels. Phase problems and dissonances in the inner ear are therefore also precluded. The difference is audible, even noticeable in the entry-level model.

Dynamic drivers of the next generation
Small but mighty. Comfortable.

A big sound, but small enough to fit your ear: the advanced driver system brings a considerably expanded sound spectrum to the ears of musicians, sound engineers and DJs. The design, on the other hand, has been optimized, checked against hundreds of ear shapes, and redesigned. The result is flat, sits securely and does not ‘carry any weight,’ even during lengthy sessions.

Small but mighty. Comfortable.
Reinvented down to the last detail

Without monitoring sound, there is no performance. The IE 40 PRO is designed to provide the necessary reliability. To this end we have even reinvented stage-compatible cabling – the internal cable duct is a unique feature (patent pending). In short: the new system meets high expectations and withstands high stresses.

Take your IEM’s from the stage to the street

Who says you can’t enjoy the comfort and quality of your in-ear monitors while on the run? Although the IE 40 PRO was designed to reproduce every nuance of your mix while performing, the same goes for listening to music on your phone or tablet. Furthermore, ear tips in multiple sizes ensure a tight seal and a snug fit, allowing for passive noise canceling and hours of comfort. So take them with you wherever you go, they won’t disappoint.
